  • Cable seal 100 includes a cable seal body 102 and an enclosure plate or cover 104 that can be affixed to cable seal body 102 by sonic welding, adhesives or other suitable fixing means.
  • Cable seal body 102 and enclosure plate 104 can be made from injection molded plastic.
  • Cable seal 100 is configured to receive and retain therein one end of a cable 106 while further receiving and clamping a segment near a distal opposite end of the cable after the cable has been looped through a latch, lock or other structure of a container on which the cable seal is used.
  • cable seal body 102 is provided with a first cable aperture or hole 108 and re-entry second cable aperture or hole 110 both at one end of the cable seal body for receiving the looped cable, and a single third cable aperture or opening 112 at the opposite end of cable seal body 102 through which the distal free end of the cable extends.
  • Cable seal body 102 is provided with concave knurled or textured side elements 114, 116 on the outer surface thereof, making the cable seal easily grasped between the thumb and forefinger of one hand of an installer even if the installer is wearing gloves.
  • Cable seal 100 is relatively thin from the front face thereof to the back face thereof so that it will sit flat against a container on which it is installed. The front and back face surfaces of cable seal 100 provide sufficient flattened area for receiving printed indicia such as bar codes or the like.
  • a through hole 118 extending through the front and back of cable seal 100 is provided for sequential packaging of a plurality of cable seals 100 on a wire, peg, cord or other suitable packaging retainer.
  • Cable seal body 102 is provided with a pocket 120 and enclosure plate 104 is provided with a corresponding pocket depression 121 on the inside thereof overlying pocket 120 together forming a cavity for receiving a cleat, knob or other enlargement 122 on one end of cable 106, with the cable then extended outwardly through first cable aperture 108. Accordingly, cable seal 100 can be provided with cable 106 preinstalled therein, with the cable retained by enlargement 122 held in and by pocket 120 and pocket depression 121.
  • the cable After being looped through the latch or other structure of the container being secured, the cable is reinserted into cable seal 100 via re-entry second cable aperture 110, and is passed through the cable seal.
  • the distal free end of cable 106 passes completely through cable seal 100 and exits via third cable aperture or opening 112.
  • the surface of cable seal body 102 immediately surrounding re-entry second cable aperture 110 is chamfered or concave, forming a well 124 angling inwardly toward re-entry second cable aperture 110 so that the cable can be inserted easily through re-entry second cable aperture 110.
  • Cable seal 100 is provided with first and second cable gripping members in the way of a metal stationary toothed wheel 130 and a metal movable toothed wheel 132, respectively. A portion of cable 106 is held securely between toothed wheels 130, 132. Movable toothed wheel 132 is operable along a channel 134 in cable seal body 102 and an overlying channel depression 135 in enclosure plate 104. Channel 134 is defined partially by an outer wall 136 angularly disposed relative to a cable path 138 through cable seal 100. In the exemplary illustration, channel 134 and wall 136 are at an angle of about 24.5 degrees to the cable path.
  • a spring 140 is retained at one end thereof in a spring shaft 142 in body 102 and an overlying spring shaft depression 143 in enclosure plate 104.
  • Spring 140 is disposed against movable toothed wheel 132 at the opposite, free end of spring 140.
  • Spring 140 biases movable toothed wheel 132 toward re-entry cable aperture 110.
  • a frangible barrier 144 which may be a breakable wall or post, limits the travel of movable toothed wheel 132 within channel 134 prior to use of cable seal 100.
  • Cable 106 is pinched between toothed wheels 130, 132 in the installed condition of cable seal 100.
  • Stationary toothed wheel 130 is fixed in both position and rotation, and need not be a circular toothed wheel but may be, for example, a serrated formation, teeth or projections on an edge or wall in cable seal body 102.
  • stationary toothed wheel 130 and movable toothed wheel 132 can be manufactured as interchangeable parts.
  • Stationary toothed wheel 130 is received in a circular well 146 in cable seal body 102 below an overlying well depression 147 in enclosure plate 104.
  • Well 146 may be of slightly smaller diameter than the tooth tip diameter of stationary toothed wheel 130 so that the teeth thereof embed in the wall-like surface defining well 146.
  • stationary toothed wheel 130 Some teeth of stationary toothed wheel 130 are exposed to cable 106 between re-entry second cable aperture 110 and cable path 138 and can be embedded into cable 106 when the cable is pinched there against by movable toothed wheel 132. Accordingly, pinching force exerted against stationary toothed wheel 130 is transmitted to and dispersed through cable seal body 102.
  • Stationary toothed wheel 130 functions as a backing body against which movable toothed wheel 132 pinches cable 106.
  • movable toothed wheel 132 pinches cable 106.
  • Other types of backing structures for the pinch point capture of cable 106 can be used.
  • An advantageous feature of the preferred embodiments shown and described is that cable 106 is pinched between the two metal toothed wheels 130, 132, rather than against and between one metal component and a plastic part. Accordingly, it is believed advantages can be obtained if the backing part is a metal insert in cable seal body 102, even if it is not a stationary toothed wheel as shown.
  • the tips of the teeth of toothed wheels 130 and 132 engage cable 106 so that the cable is held between toothed wheels 130, 132 and does not become dislodged therefrom. If pulling force is applied against the cable seal 100 in a manner to apply tension in the loop of cable 106, in an attempt to withdraw the distal end of cable 106 from cable seal 100, movable toothed wheel 132 traverses along channel 134, engaged against and walking along wall 136 of the channel. Movable toothed wheel 132 thereby moves closer to stationary toothed wheel 130 further decreasing the space between the toothed wheels such that the cable is pinched more tightly between the toothed wheels.
  • a distance between outer wall 136 and stationary toothed wheel 130 near the end of channel 134 at re-entry second cable aperture 110 is less than the diameter of movable toothed wheel 132 so that the teeth of movable toothed wheel 132 embed into wall 136 when movable toothed wheel 132 is moved to the end of channel 134.
  • movable toothed wheel 132 remains at the end of channel 134 with some teeth of the toothed wheel 132 embedded in wall 136. Toothed wheel 132 is held near re-entry second cable aperture 110, blocking the cable aperture and preventing re-insertion of the cable, as shown in Fig. 13. Further, if cable 106 is forcibly withdrawn from cable seal 100, the distal end of cable 106 will be frayed as it is pulled through the narrow opening between stationary toothed wheel 130 and movable toothed wheel 132 when movable toothed wheel 132 has been pulled nearest to re-entry second cable aperture 110. The frayed cable end is difficult to re-insert into cable seal 100, and provides visible evidence of tampering.
  • Enclosure plate 104 can be provided with a sealing lip 150, and is received within and upon a ledge 152 in cable seal body 104.
  • FIG. 14 illustrates a cable seal 200 having a cable seal body 202 that is otherwise similar to cable seal 100 and cable seal body 102 except that cable seal body 202 does not include frangible barrier 144.
  • Components of cable seal 200 that correspond to similar components in cable seal 100 have been identified with the same reference numerals as those used for cable seal 100.
  • Cable seal 300 includes a cable seal body 302 having a modified spring retention shaft 342 that includes an outer edge protrusion 343 at the opening to spring retention shaft 342.
  • Protrusion 343 urges the exposed portion of spring 140 toward cable 106 so that the rolling movement of movable toothed wheel 132 along wall 136 as a spring 140 is compressed does not cause spring 140 to be pulled over.
  • Protrusion 343 provides improved lateral stability in the portions of the spring 140 that are exposed outwardly of spring retention shaft 342.
  • Cable seal 400 illustrated therein is similar to cable seals 100, 200 and 300 described previously. Accordingly, components of cable seal 400 similar to components in cable seals 100, 200 and 300 are identified with the same reference numerals. Cable seal 400 includes a cable seal body 402 having a further modified spring retention shaft 442 angled such as to offset the distal end of spring 140 from the diameter of movable toothed wheel 132.
